We needed a new air conditioning unit. They were very helpful in answering our questions and scheduling a convenient appointment installation to fit our schedule. We have been very satisfied and comfortable ever since.

Onofreo was an absolute pleasure to work with. Their team is knowledgeable, professional and prompt with their service. They have fixed small and major issues for our commercial property. We continue to use them time and time again.
Elizabeth “Liz” Carriero
They installed 2 mini split heat and ac units in my home back in July 2025. The process was somewhat easy from getting the estimate to the installation. The scheduled employees were on time for all appointments. The installation only took one day and the workers where careful about their surroundings and cleaned up after them self.
Mark Bishop
Onofreo Home Comfort replaced my 35 year old oil boiler with a new natural gas combi boiler. They added a 3rd zone. They updated all thermostats. The workmanship on the natural gas piping and installation is top notch. They also removed the old oil boiler and 250 gallon oil tank. There was one issue after start-up, which was corrected after a few tries and we have been trouble- free ever since. Overall a very positive experience from initial sales call, through the estimating phase and concluding with expert installation and effective problem resolution. I would recommend Onofreo to anyone looking to upgrade their home heating system.
Marissa Carbone
I had an issue with my furnace last year and a local company told us it had a crack. Since the furnace was fairly new, we called Onofreo for a second opinion. They quickly determined there was no crack — just a small faulty part — and fixed it on the spot for a fraction of the cost. We now use them for our annual maintenance, and they’ve been great! Highly recommend
